2 Claims.

(Cl. 23S-144) (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The invention described herein may be manu- Iactured and used by or for the Government of the United States for governmental purposes without the payment to us of any royalty thereon. AThis invention relates to improvements in perforated record-controlled tabulating machines.

The object of the invention is to provide a simple, durable and eihcient mechanism for printing the totals of the tabulations in line form divided into columns, properly separated upon a removable record sheet and for automatically and quickly resetting the numeral wheels, after each print.

The invention about to be described has a special relation to the-disclosure in the application Serial No. 49,408,.led November 12, 1935, by

Eugene M. La Boiteaux, which eventuated in Patent No. 2,035,752, dated March 31, 1936 for Improvements in tabulating machines,-and in order that our invention may be more readily understood, we have duplicated much of the illustrations of the mechanism of the La Boiteaux invention, but make no claims thereto or toparts thereof, except where certain elements of said I invention are necessarily and legitimately involved in combinations other than those devised by La Boiteaux.

In the drawings illustrating the invention: Figure 1 is a top plan view of the tabulating machine to which our invention is applicable,

Referring to the drawings, the numerals I and 2 designate the side plates of the machine andi the hase thereof. In the plates are journaled various shaits,some extending entirely across the machine, and others stub,-some continu- 55 ously revolving-some intermittently rotating, and others having merely an oscillatory movement. 'I'he shafts 'carry gears, and sprockets, cams and eccentrics, all arranged and timed for coordinative action.

Referring particularly to Figures 1 and 3, the numeral d designates the power-transmitting feed roll of the analyzing unit or mechanism of the machine. It is mounted on the transverse shaft 5l having bearings in the side plates Il and 2 and has nine cam-sided recesses, 6 arranged in longitudinal rows and circumferential columns, as shown best in Figure l. The ends of the shaft carry gears 'I and l', the gear 'I meshing with an idler gear below it, which in turn meshes with a power gear on the shaft 9 mounted in the side plates I and 2, the power gear serving to transmit rotation and power to the analyzing roll Q through the intervening gear. The 'gear 'I' of the roll 4 meshes with a similar gear directly below it, the latter gear beingI on the shaft I of a roll II directly below the roll d and provided with an annular groove II there-around for the reception of the heads of the analyzing levers. 'I'he shaft I0 of the lower roll is not mounted in the side plates, but in the ends of oppositely-disposed links pivoted to the inner sides of the side plates, and this shaft has but one gear and that in mesh with the gear I of the analyzing roll d. The links in which the shaft I0 have bearings are suspended by stretched springs so that the gear thereon will mesh yieldingly with the gear l', and the rolls-are keptin complete longitudinal contact with each other, except when a card is passing between them, and the card or perforated record which is designated by a, Figure 3, is so thin that it has no appreciable eifect upon the relation between the gears.

Next to the analyzing roll and its companion, which are feed rolls and more, are feed rollers I 2, adjacent which, or a part of which, are gears i3. 'I'hese upper rollers and gearsare mounted upon stub shafts in oppositely-disposed hangers pivoted to the inner sides of the side plates, the

hangers being urged downwardly by springs Id so as to keep the gears yieldingly in mesh with the gears on the shafts of similar rollers located directly below the rollers I2.

Other feed rollers I and I6 are provided on a transverse shaft I1 carrying a gear I8 which meshes. with other gears appropriately arranged and driven, and it is enough to say that these feed rolls and rollers are duly arranged with relation to a feed hopper II in a stacker hopper I8'.

None of the elements, however, that have been described, form any part of this invention, in

. themselves or specifically.

In front of the analyzing roll 4 and its grooved companion roll II, is a transversepivot bar I9 extending entirely across the machine and suitably secured to the side plates. This bar is formed with numerous recesses 20 in which are mounted pivotally, on transverse pivot pin 2 l, numerous analyzing levers 22, one lever in each recessand in which the levers are free to rock and are guided and held in true vertical augment. The horizontal arm 23 of the lever is formed with a head of the shape of the cam-sided recesses 6 in the analyzing roll 4, into which recesses the heads are arranged to extendwhenever a hole in itis attached the spring 25 with its other endv aoeaear fastened to a transverse plate 2l secured to the bar, the spring obviously urging the head 2li of the lever always upward so that it will quickly enter one or another of the recesses in the roll 4 when available through a perforation; otherwise the spring will hold the head firmly against the card while running between the rolls at points where there are no perforations in the cards. The numeral 27 designates what may generally be regarded as the tabulating unit, which is located at the front of the machine. It includes a continuously revolving shaft 28 mounted in open end bearings in the standards 28' and upon which shaft are frictionally mounted numerous numeral wheels 29, and for each wheels there Aare two anchors, one an active anchor 30 which operates throughout the tabulating operation to permit the wheels to rotate with the shaft or not, accordingly as the anchor is controlled by the analyzing means; and the other a transfer anchor 3| actuated when a particular wheel has counted up to its capacity to transfer the excess tothe adjoining wheel, the like of which is found and fully described in the La Boiteaux application above referred to. But the specific anchor controlling connections between the analyzing unit and the tabulating unit are, so far as we are aware, new with us. An element in these-connections is a push bar 32, with its rear end 33 positioned so it will be engaged and moved longitudinally in one direction (forward) by the lower end 3G of the analyzing lever, ac-,

rockable anchor-control arm on a shaft 39 mounted in .suitable bearings in the plates 40 and 6I, and this shaft forms a pivot for all of the numerous control arms. The upper end of the control arm is provided with an open end recess 112 for the reception-of the pin 31, thus providing a readily removable connection between the push rod and'its control arm, which makes feasible the quick and expeditious rearrangement of the push rods according to' the exigencies of tabulation of different card-column arrangement. The lower end 43 is arranged to engage the rearwardly-extending arm M of the active anchor to rock it on its pivot 44' to disengage it from a tooth on a numeral wheel against the influence of a spring 45 to permit the wheel to revolve with the shaft and count a number (from 1 to 9), according to the digit number-of the notch in the analyzing roll from which the head 24 has been expelled, the digit number of the perforations in the card always corresponding with the digit number of the recess in the roll. For instance, the head is, in Figure 3, in the digit recess 5 and when vexpelled therefrom by the further revolution of the roll, during which time imperforate portions of the card will be passing over the'head; the impulse given the push rod by the analyzing lever will anchor out of engagement with a tooth of the wheel and hold it out until the wheel moves with the shaft 28 to count 5.

The push rod is normally urged rearward by the spring 35, connected at one end to the control arm and at the other to a angeon a transverse plate 47, secured to the side plates 40 and 4I, and the lower end of the controll arm is normally in position to rock the anchor away from the wheel.

The analyzing roll has a groove 48 therearound, Figures 1 and 11, which is in vertical alignment with the similar groove II in the roll I I, and between the rolls 4 and I I and within the groove extends the horizontal arm of the 11ocard lever 50 of which there is but one .and which is pivoted at I in one of the recesses 28 in the cross bar I9-, with its other vertical arm extending downwardly and to which near its end, is pro,- vided a lug 52, the purpose of which will be later described.

In Figures 11 and 12 the lever is shown in nocard position, which is its normal position, to which it is constantly urged by the spring 53 Which has one end connected to the lever and the other to the plate 21, which plate is also anchored for the various springs that keep the head ends of the analyzing levers raised. The card position of the lever 50 is shown in dotted lines and in which position the end of the Vertical arm of the lever is out of the path of movement of an oscillating arm 54 integral with a sleeve loosely mounted on the continuously revolving shaft 9. To this sleeve is valso secured another arm 56 carrying at its end a roller 51 that runs on cam 58 keyed to continuously -rotating shaft 58 which has certain eccentrics thereon for operating the card feed through appropriate connections, there being a reciprocating arm 60 connected with a suitable eccentric and also with a rockable varm 6I that has a sleeve 62 loose on shaft 63, whose ends are mounted in side plates I and 2. The upper end of the arm 6I carries the card feed knives which push the cards between the rolls one after another. When no cards are going through the machine the no-card lever is in the position shown in full lines, Figures 11 and 12, and the lower end of the no-card lever has been brought by its spring in position to engage the end of the arm 54 latching it against oscillation and causing the arm 56 to remain in its highest position with its roller out of reach of the cam head 64 of the cam 58. 'Ihe oscillating arm 54, cam 58 and arm 56 we utilize to actuate a counter or register 65, Figure l. When no cards are going through, the oscillating arm 54 is latched, but as soon as a card passes between the rolls 4 and H, the horizontal arm 49 of the no-card lever will be depressed, rocking the lower end of its vertical arm out of latching contact withy the end of arm 54, permitting the arms 54 and 56 to be rocked by the cam 58 as long as there are cards passing through.

AOn the end of the arm 54 and just far enough thereon to let the latching end 66 protrude a little beyond it, is a bracket 61 securely held to the arm by a screw 68. To the side of this bracket at 68' is pivoted the lower end of the link 69 pivotally connected by a slot and pin connection with a short oscillating link mounted on the shaft 1I of the card counter or register. It has been seen that so long as the no-card lever occupies a position shown in full lines, its normal position, no cards are passing through, and the arms 54 and 56 are still, the roller 51 on the arm 56 being out of the reach of the cam head 64, even though this cam be turning, but as soon as the cards start through, depressing of the arm 48 of the no-card lever will disengage its Vertical arm from the end of the arm 54, letting the roller 51 down on the cam 58, which will from that time on rock both arms 54 and 56, until again at appropriate times the arms will be latched; but in the meantime an oscillating movement is imparted to the link 18 through the long link 65, thus loperating the register, and obviously only when the cards are passing through the machine.

Pivoted to the side plates are two oppositelydisposed arms 66 connected by a cross piece 65" and outside of the plate there is secured to the pivot of the arm a lever 61', Figure 10, to which is attached a spring 61" pushing the lever up and consequently forcing the arm 66' in the same direction. One of the arms 66'-the one adjacent the no-card lever 50--carries a lug 68" for engagement by the head of a curved arm 69 pivoted on a boss 69'? on the side plate I. The other end of the arm has pivoted in its bifurcated end a block 68', Figure 13, which has a. narrow projection 10 thereon, the block being held normally in the position shown in the gure by a coiled spring 18", there being secured to the side of the block an inclined plate 1I. There is a continuously oscillating arm 1 I like 6I, and on the opposite side of the machine from 6 I or on the same side with the oscillating arm 54, and this arm 1 I is arranged to contact with the projection 1li of the block when the vertical arm of the no-card lever is in its no-card position, or that shown in full lines in Figures 11 and l2, and this contact between the arm 1I and the projection on the block which is carried by the arm 68 is suilcient to disengage its head from the lug 68" and allow the arms 66 to rise under the influence of the spring 61". When the lever 61', Figure 10, is pressed down, the arms 66 will be lowered, permitting the head of the curved arm 68' to ride up over the lug 68 and thereby hold the arms in lowered position. This action lowers the cardlifting plate 80", Figure l, to card feeding position and when the motor is started and the first card passes between the rolls 4 and II, the horizontal arm of the no-card lever 50 will be pressed down by the card, thus moving the vertical arm forward to dotted-line position, Figure 11, which will cause the lug 52 on said arm to engage the inclined arm 69 and link 10, operate the card register as long as the horizontal arm of the no-card lever remains depressed.

Printing mechanism The numeral 12 designates a swinging housing for the printing mechanism and the ribbon and paper feed mechanisms. It is provided with two oppositely-disposed plates 13 at its forward side edges through which the shaft 14 extends and upon which the housing and its contained parts pivot, so that the housing may be swung to and from the main body of the machine, there being means to be described for latching the housing to the machine body.

A cam which extends practically for the entire width of the machine is provided with a sharp drop 16, the cam being fast to a shaft 11. Mounted on the right-hand end of this shaft is a sprocket 18, Figure l0, opposite a sprocket 19 fast on a shaft 14, supported in a hanger 8l secured to the under side of the base of the machine, the sprockets being connected for joint movement by a sprocket chain 82, the ratio of the sprockets being such that they will rotate at the same rate. 'Ihe numeral 83, Figures 5 and 6, designates a printing hammer of which there is one for'each numeraly wheel on numeral wheel assembly. It is mounted and rocks on a shaft 84 supported in the side plates of the housing, the hammer being provided With a contact head 85, a downwardly-extending cam-engaging arm 86, and a forwardly-extending arm 87, to which one end of a spring 08 is attached, the other end of the spring being .attached to the cross piece 89 on the top of which lis a plate 90 which extendsentirely across the housing and has therein numerous recesses 9| in which the hammers work and by which they are given support against lateral distortion. The cam l5 revolves in the direction of the arrow, and when the end of the hammer arm 86 drops into the deep portion or drop H6 of the cam, the strong spring 88 will force the hammer against the paper 92 to take a print from whatever character that is at the printing point on the numeral wheel, a printing ribbon 93 being interposed between the paper .and the character. When the arm 0S leaves the drop I6 and rides on the outer periphery of the cam, the hammer head will be moved from its printing position, as shown in full lines in Figures 5 and 6. The movement of the hammer in printing is very quick due to the steepness Iof the drop in the cam and the strength of the spring 88. The two dotted lines e (Figure 6) of the dropflS indicate the position of the cam and the arm 80 just before the parts have been set in motion to print, and immediately thereafter, the space between the dotted lines showing the short distance that the cam travels in order to make a print. It is not desirable at all times to permit all the hammers to operate, as in cases where all of the numeral wheels are not beiing used, and to hold any one or any number of the hammers out of action, we have contrived the retaining device indicated by the numeral 00 and illustrated in Figure 5b. This device fits on the cross member that spans the space between the sides of the housing and is slidable thereon, being held to the cross member by friction. It is provided at its upper end with a short laterally-extending flange or ledge 9d that is positioned to overhang the front end of the arm 8l of any hammer that is to be rendered inactive, and when not required, it may be slid to one side out of the Way of all hammers. The device shown is of a width that adapts it lfor controlling one hammer, but it will be understood that its width may be varied to control any number of hammers as the necessities may require, as for instance, when it is expedient to employ separate groups of numeral wheels composed of any desired number of wheels to conform to the, number of group columns of the card.

The ribbon feed and shift mechanism described in part of the following, forms the subject-matter of our application Serial No. 70,718, filed March 25, 1936-a division of the present applicationand which eventuated in Patent No. 2,041,637, dated May 19, 1936.

Theribbon spools are designated by the numeral 96, Figures 1 and 6, and they and the paper roll 9| are rotated by the verticallyy movable actuating lrod 98 having a shoulder head 99 at its upper end for engagement with the teeth of the paper roll ratchet |00, and a slot 0| in its lower end for the passage of a headed screw |02 by which slot and screw arrangement the rod is guided in its up and down movements and at the same time permitted.

to swing slightly, as is necessary in its operation. The rod is further formed with a laterally-extending arm |03 having a wide and somewhat elongated slot therein for the reception of the cam |043 mounted on the shaft 11 with the cam l5, the cam |04 serving to give to the rod the desired vertical movement.' Pivoted to the rod about midway thereof is a spring-urged pawl |05, the head of which is arranged to engage the ratchet wheel |06 on a shaft |01 extending entirely across the f ront side of the housing, and

carries the beveled gear |08 which meshes with similar gear |09 on short vertical shafts ||0 of the ribbon spools, the shaft being suitably sup ported in bearing brackets on the cross piece 89. The shaft |01 extends across the machine and motivates both spools. The cross piece 89 is slotted for the passage of the rod 98, the slot being of sufficient width to permit of the free slight swinging movement that the rod must have, and which is caused by a flatsided cam on shaft 2 and whose :dat side bears against the rear edge of the rod 98, and against which the rod slides in its slight vertical movement. Connected with the Ishaft ||2 is a handle ||3 by which the cam may be turned to rock the rod 9B on its fulcrum |02 to move the rod head away from the ratchet |00 which ratchet is mounted on the paper roll shaft H4. The cam |04 imparts vertical movement to the rod -98 and raises it the proper distance to enable' the rod head and the headof the pawl |05 to engage the on-coming teeth of the ratchet Wheels |00 and |06, and then lowers the rod to turn each of the wheels the space of one tooth, thus turning the ribbon spoolsY and the paper roll accprdingly.

Adjacent each ribbon spool there is a pivoted link ||5,each carrying a laterally-extending lug ||6 to each of which is attached a roller These rollers bear against the ribbon on the spools and` the end of each link is connected by an adjustable connection ||8 to a connecting arm H8' having a hole ||9 centrally located therein for the reception of a pin I I9' on the upper plate |20 pivoted at |20' to a central extension |2| of the cross piece 89 of the housing. This plate is provided with an arcuate slot |2|' for the passage of a stud |22 to which one end of a spring |22 is connected, the other end of the spring being connected to a link |23 pivoted at |23 to the upper plate. Interposed between lthe flat face of the lextension |2| and the plate |20is another plate |2B, which rocks or pivots on the. stud |22. This intermediate plate carries a pin .of the upper plate, and the lower plate has similar spurs |25' arranged to engage one or the other of the shoulders |26 of a block |26' on the cross piece.v The lower pivoted plate |24 is slotted as indicated at |26' for clearance of the pivot |20', the lower portion of which passes through the roomy slot in the lower plate and into the extension |2|. The forw-ard end of the plate |26 is notched in two places as indicated at l2?, the notchesbeing for the purpose of receiving, when the plate is in one or the other of its extreme rocked positions, the spring-back ball |28', the ball protruding partly out of a recess in the block |2| for the purpose of stabilizing all of the parts in their extreme positions. There is a pin i9" on the under side of ,the bottom plate that extends through elongated slot |20" at the forward edge of the cross pier c and this pin extends into the annular groove of a disk |2| fast to a sleeve |22 slidable on the shaft |01. Supported in hangers |23" are two short sleeves ld" which surround and are loose on shaft lill, and each sleeve carries at its outer end the beveled gear |08 and on its inner end a toothed clutch member arranged to cooperate with a similar member 26" carried at each end of the slidable sleeve |22, there being in the sleeve and adjacent the grooved disk a slot for the passage of a pin |21 carried by the shaft, thereby assuring the revolution of the sleeve with the shaft and at the same time permitting the necessary lateral movement of the sleeve to allow its clutch members |26" to engage and disengage the corresponding members carrled by the short sleeves |24", by which arrangement it will be seen that the shifting of the sleeve |22 to either extreme position will cause one or the other of the clutch members |26" to engage one or the other of the similar members |25" on the inner ends of the short sleeve |24 and thus rotate the engaged sleeve to rotate its gear |08 to turn, through gear |09, its ribbon spool, the bevel gears |08 and I 09 being alw-ays in mesh. I

The way the ribbon shift works is this: 'I'he connecting arm |8 is shifted laterally and rocked slightly by the building up of the ribbon alternately on the spools. The rollers on the links bear upon whatever ribbon is on the spools, and as shown in Figure 1, the shift has just been made from the left spool to the right. From now on as the ribbon builds up on the spool 96 its link ||5 will be very gradually rocked toward the center of the machine, likewise moving the arm ||8' to the left until the side of the opening |9 engages the pin ||9 on the upper plate |20, and from that time on and as the ribbon on spool 96' builds up, this top plate will be very slowly turned on its pivot |20' until the pin 9 has passed the center when the spring |22 will in-' stantly act to accelerate the lateral movement of |20 and cause a spur |25 to strike the pin I 24' carried by the lower pivoted plate and rock the plate on its pivot |22 until a spur |25' engages a shoulder |26 of the block |26', the quick shifting of the lower plate causing its pin ||9" to swing laterally to shift the sleeve |22" through the medium of the grooved disk I2|" to slide the sleeve sufficiently to disengage a clutch member from one of the short sleeves and bring its other clutch member into engagement with the clutch member of the opposite short sleeve. The stud |22 serves a three-fold purpose. It is a pivot for the lower plate |24; an anchor for the spring |22', and is means to limit the throw of the top plate by reason of its slot connection with the stud.

Pivoted in the left and right-hand plates 13 and 13', Figures 1 and `2, is a cross rod |30 whose ends extend through the plates and to each end is secured a latch |3| and |32, which are rigidly secured to the rod. Each latch is provided with a thumb piece |3|" and |32', at one end, and al catch |33 at the other, arranged for engagement with and disengagement from similar retaining pins 34. When either or both of the thumb pieces are pressed, two separate movements will occur. First, the rear ends of the latches will be 4raised out o f engagement with the retaining pins to assume the position shown in dotted lines,v

Figure 5, to permit the entire housing 12 to be swung forward toward the operator, or to the position shown in dotted lines, Figure 10. The rocking movement of the latches rocks the shaft |30 to which is attached near the side plates 13 and 13' the arms |35 and |36 whose lower ends are bifurcated to receive pivoted paper rollers |31 and |38, Figure 1. The paper roller carrier arms are integral with the sleeves |39 which are loose upon the shaft 30, but have very little movement thereon, their movement being limited in either direction by the sides of recesses in the sleeves which engage the lugs |4| carried by collars |42 secured to the shaft by set screws |43, lateral movement of the sleeves being otherwise limited by collars |44 on the shaft. The difference in the size of the lug |4| and the recess |40 permits slight lost motion between these parts so that when the rod |30 is turned until the lug engages the front side of the recess, the catch |33 will be clear of the pin |34, and further movement of the rod will cause the sleeve to turn with the rod, moving the paper rollers away from the paper. to normal position there are provided two plungers |45, one at each side of the machine. These plungers are spring-backed and retained in the bores of barrels |46, which plungers are in engagement with the thumb pieces of the latches, urging them always to cause their catches to embrace a pin |34 to lock the housing 12 to the main body of the machine.

'Ihe paper 92 passes in front of the characters on the numeral wheels and has interposed between it and said characters the printingribbon 93, and the arrangement is such that after a print, the paper continues up over the paper roll 91.

Resetting mechanism After a printing operation it is necessary t0 reset all of the numeral wheels to zero preparatory to a new ru of cards, and now that the elements containe in the housing have been described, we come to the parts contained in the front of the main body of the machine adjoining the swinging housing, some of which are contained between the plates 13 of the housing.

The numeral |48 designates a lever pivoted at |49 and which is formed with a horizontal arm |50 and an inclined arm |5| there being a thumb piece |52 on oneend and a catch |53 at the other, there also being a pin |54 extending laterallyl from the inclined arm and in position to engage the sides of a recess |55 in the base 3, through which this end of the lever extends, the pin serging to limit the downward movement of this end of the lever, it being urgedto its downward position by avgspring |56 interposed between the base and the under side of the arm |46. Mounted on the shaft 14 and at one side of the machine, Figures 5, and 6, is an eccentric |49 surrounded by an eccentric strap |50 that has an arm |60 which extends obliquely upward through a recess in the base, where, thereab'ove, it is arranged to actuate a bell crank lever |6| to control certain cams which in turn control the numeral wheel controlling anchors, of which mechanism more will be explained presently. Integral with the cam strap |50 is an arm |62, to which is pivoted a dog |63 with a tooth |64 on one end and a shoulder |64' at the other, the catch being arranged to engage the shoulder of the lever anding shaft 14, which we have seen is geared to the shaft 11, upon which'the cam 15 which actuates the printing hammer, is mounted, and when For returning these parts the joint revolution of the shaft, arm and dog is completed, the arm |60 will have rocked the bell crank lever |6| fast upon the shaft |6i to the position shown in Figure 6, against the inuence of spring |60', during the first' part of ythe revolution of the eccentric, and returned the arm to its normal position, or that shown in Figure 5, in the final part of its revolution.

The movement from and return to normal position of the bell crank |6| has operated certain cams that control certain movements of the numeral wheel anchors. Referring to Figures 3, 4, 5 andl 6, the numeral |61 indicates a gear fast on lthe shaft |6I with the bell crank. This gear meshes with an intermediate gear |60 on a stub shaft |69, which latter gear in turn meshes with another gear |10 on shaft |1I. Both the shafts IBI and |1| extendentirely across the machine and between the plates in which they are mounted take the form of cams, the cam |12 being on or a part of shaft |6I', while cam |13 is on or a part of shaft |1|. These gears and consequently the cams do not at any time make a complete revolution, their movement being oscillatory and brought about by the rocking movement of the bell crank, whether applied manually or automatically, the automatic character of the operation being that which is given to this part of the machine by the mechanism we have devised, or shaft 14 and mechanism carried thereby, and that for controlling its movements.

The numeral |14, Figures 3, 4 and '1, designates a shaft suitablymounted in the side plates at the front of the machine,'which shaft extends entirely across the machine and carries numerous spire-longitudinally offset cams |15, one for every numeral wheel. These cams are arranged to engage a cam |16 carried by each of a numerous lot of links |11 swinging in recesses |19 upon a common pivot |18 that passes through the numerous tines |80 of a cross piece |8| rTo the lower end of this link and pivoted at |82 is a horizontal arm |83 having at its free end an inclined portion |84 that merges intoa narrow end |85 adapted at times, as will appear, to ride on the lower end |86 of the downwardly-extending arm |81 of the transfer anchor 3|, and at other times engage the notch |88 in said arm to rock the anchor on its pivot, there being a roller |88 adjacent the arm for engagement with the inclined portion |84 to lower said arm at the proper instant in the operation of this mechanism. The link |11 is held against the cams by a spring |89 and a spring |90 always tends to lift the arm |83, and a spring 3|" always urges the head 3 of the transfer anchor to normal position toward a portion of the numeral wheel assembly. There is a transfer anchor 3|, and an active anchor 30, and a set of links and arms |11 and |83 for each numeral wheel, all suitably guided and braced against any unwanted movement in their various operations. The active anchor is formed with a head |9| for engagement with one or another of the teeth |92 of the toothed disk |93, and the transfer anchors head 3 i is arranged to be engaged by and released from, at predetermined points and for predetermined times, the lug |94 on the lug disk |95 (dotted lines Figures 4 and '7) of the numeral wheel assembly, which as we have seen, is composed of the numeral disk 29, the tooth disk |93 and the lug disk |95, all compactly held together in laminated form and rotating as one upon the continuously rotating shaft 28 upon which the numerous wheel lassemblies are frictionallyrmounted in such a way amasar that they are compelled to rotate with the shaft except at such times as they are held therefrom by the anchors. Each anchor 30 has thereon a stud |96 in position to be engaged by its companion transfer anchor to disengage the active anchor from the wheel as the exigenciesrof the operations require.

In Figure 3 the head 24 of the analyzing lever has entered digit 5 in the analyzing roll, through the digit 5 perforation in the card, but it will be expelled therefrom upon the further rotation of the roll by the cam action of the recess and will ride on the card until the digit 1 recess in the analyzing roll has passed. The rear end 33 of push rod 32 is held normally against cross piece 33 of slotted arm 33 by a spring 34', which arm is rocked at timely intervals. This arm carries in the slot therein a slidable plate 34 for engagement at appropriate intervals with the analyzinglever 22 to hold its head 24 out of engagement with the power roll 4, against the tension of spring 26. The position of the power roll 4 is such with relation to the head 24 of the analyzinglever 22 that `when the head is cammed out of the recess (which represents digit 5 in Figure 3) the push rod will be kicked forward against the action of spring 35 causing rocker arm 38 to depress arm 44 of tooth wheel anchor 30, rocking it on its shaft 44 and disengaging its head 9| from a tooth on the numeral wheel, and in the position illustrated, allow the wheel to revolve a distance of ve teeth, which action has been caused by the head 24 passing through perforation "5 in the card and its instantaneous expulsion therefrom. At about a point between 0 and "1. designations on a card, arm 33" will, by properly timed mechanism, be lowered depressing push rod 32 and taking its rear end 33 out of the way of the analyzing lever. At this moment spring 35 will urge the push rod rearwardly, allowing the rocker arm 38 to release the anchor 30 and under the in- 2lil fluence of spring permit it to engage the sixth or on-coming tooth to arrest the movement of the wheel, after five teeth have passed, counting five on said wheel. At this time the slidable plate 34" will be forced forward, resetting the analyzing lever and holding its head 24 out of and away from the roll 4 until the forward longitudinal edge of the next card is a short distance under the roll,

when plate 34" will be withdrawn, allowing the head 24 to rest and ride on the card until a perforation is reached, when the above cycle will be` repeated.

'I'he distance between the digits "9 and "1" represented by the recesses .6, in the roll is equivalent to the distance between digits "9 and 1" on the card. The distance of movement of the smooth portion of the roll is equivalent to the distance between "0 designation on the card just tabulated and the forward edge of the card to be tabulated. The head 24 is held out of and away from the roll during the passage of its smooth portion past the head.

When the numeral wheel has counted up to its capacity or nine the lug |94 on the lug disk will trip the transfer anchor 3|, forcing its head 3|' backward only a sulclent distance to permit the narrow portion |85 of the arm |03 to drop in the notch |88 of the depending arm |81 of the transfer anchor'. After this action has taken place and the notch is occupied by the end of the arm 83, both the link and arm |11 and |83 will be pushed forward by the cam |15 acting on the cam |16 on the link, thus forcing the upper end of the transfer anchor 3| backward to engage the stud |96 on the next anchor 30 to the right, which allows a wheel to revolve until the head I9| catches the next on-coming tooth, which, when the first and second wheels from the left are considered, the first has added up to its capacity or nine, one will be transferred to the second wheel to make a total of ten. Until the depending arm |81 of the transfer anchor has been rocked forward .the narrow portion of the arm |83 will merely ride back and forth under the lower end of the anchor arm without any definite action taking place, but when the notch is occupied by the narrow portion of the arm it assumes the position shown in dotted 1ines.-Fgure 4, and will move the anchor to its new position or that shown in dotted lines, but continued forward movement of the arm brings the inclined portion |84 against the roller |88 thus depressing the arm and causing its end to again ride aimlessly against the end of the anchor, thus allowing both of the anchors to return to normal positions under the infiuence of their respective springs. This is timed with the action of the cam on shaft |14, so that the anchor 30 will permit only one tooth to pass under it before it returns to normal position, and at this time the arm |83 and the anchors are in position to start a new cycle, or in the positions shown in Figures 3 and 4.

Referring to Figures 4, 5, 6 and 7, when the arm |60 is raised it rocks the bell crank lever |6| against the influence of a spring |60' and rocks gear wheel |61, thus turning cam |.12 and also the idler gear |68, which idler in turn, turns the gear |10, which turns or rocks the cam |13, the movement of gears |61 and |10 and consequently the cams |12 and A|13 being in the forward direction. The cam |13 bearing on-the arm 44 of the anchor 30 releases its head |9| from the tooth |92 (Figure 7) and when released the numeral wheel assembly is permitted to revolve with the shaft 28. As long as the head of the anchor is free from the teeth of the assembly, the assembly would continue to revolve with the shaft, but due to the'fact that the head 3|' of the transfer anchor is inthe path of movement of the lug |94 on the lug disk. and the head being held forwardby the cam |12, taking the position shown in Figure '7, locks the anchor, and as the numeral wheel shaft and wheels continue to rotate in their normal direction (forward) the lug contacts with the transfer anchor head and stops the assembly.

Obviously, due to the accumulating process, different numerals will be in line in printing position, and momentarily held there for the print which is accomplished quickly at the beginning of the reset movements. and although the printing and reset movements of the parts are set in motion simultaneously by the same means (the pressing of the lever |48) their operating cams are sro arranged, and formed as to give time for the printing operation to have been accomlished, with time to spare for the orderly completion of the resetting of all the numeral wheels.

At the time the print is made and due again to the accumulating process, the lug |94 on the lug disk of the different numeral wheel assemblies will be at different points in their paths of rotation, but as a lug and transfer anchor head engage, that particular wheel assembly will be stopped until nally all have been stopped at the same relative position. The parts are arranged and timed so that when the lugs are held by the transfer an-- chors the zeroes of the wheels will be in line at the point b (Figure 7), but when the bell crank |52 is pressed to bring about a revolution of the shaft 14 and the parts carried thereby, the shaft 11 and cam 15 thereon will also be rotated. The two dotted lines e, Figure 6, of the drop 16 indicate the position of thecam and the extension 86 of the hammer before the thumb piece has `been pressed and immediately thereafter, the

space between them showing the short distance the cam travels in order to take a print. However, as before stated, the spring 88 is strong and the movement of the cam fast, and as these two shafts 14, 11 rotate with their operative parts, the drop in the cam will be brought in position to let in the arm 86 of the hammer and permit the spring to snap the hammer forward to make a print, a further movement of the cam withdrawing the hammer and the further movements of the parts controlled from the shaft 14, immediately completes the reset operation through the operation of the bell crank |6| and the parts controlled thereby to permit all of the wheels to be brought to zero preparatory to a new card run.

Motor starting mechanism The parts, Figure 12, are shown in no-card position and they' will remain in thisA position whether the machine is running or not so long as no cards are passing through, but we have associated with these parts a novel motor starting mechanism put in operation by the depression of the lever 61.. The pressing of this lever lowers the arm 66 to lower the card-holding plate 80 (Figure 1) to bring the stack of cards thereon down to position to be engaged by the feed knives.

The lever 61' carries on its inner side a roller |91 for engagement with the beveled portion |98 of a starting lever |99 pivoted at 200 to the side plate 2. The lower end of this lever enters the pin guarded recess 20| of the head 202 on rod 203 that slides i`n a bore 204'in a block 205 secured to the under side of the base of the machine, there being in the block a slot 206 for the passage of a pin 201 carried by the rod. This pin is arranged for engagment with an elongated iin or lug 208 carried by a collar 209 secured to the shaft 14 when the rod has been moved forward by the rockingof the lever |99 to bring the pin 201 to the position shown in dotted lines, Figure 15. The rod 203 has a depression 208 therein, in which is a ball 209', upon which rests another ball 2|0, the latter protruding slightly'above the rim of a recess 2li in which the balls are contained, the upper ball being in contact with a spring element 2|2 fastened to the block and Whose free end carries a button 2|3 of non-conducting material. When the rod 203 is moved forward, the lower ball will be squeezed out of its depression in the rod and force the upper ball against the element 2|2 and cause it to close the circuit between the two terminals 2|4 and 2 I5 fastened to the block 2|@ of insulating material, allowing the current to flow through the wires 2|1, 2|8 and operate the motor 2|9, there being interposed between the motor and the current source a fuse 220 and a manually-operated switch 22|.

The downward movementv of the lever 3l' causes the lever E99 to move the rod forwardly to dotted-line position to bring the pin 207 to position to be engaged by the lug 208 on the collar 209 on shaft 14, which shaft revolves only when the reset mechanism is operated and then makes .Y but one revolution during which the pin will bel engaged by the lug to force the rcdto its circuitbreaking position which is that shown in full lines.

So that the operator may be relieved of the necessity of lifting the entire weight of the swinging front part of the machine, there is provided (Figure 2) a retarding means-which includes a rod 2M slidable in hangers 222 and 223 fastened to the under side of the base. To the forward end of the rod is attached a chain 2313 that is made fast to 1asprocket 235 which surrounds shafts 'M but is entirely independent of the shaft, the sprocket being secured to the side plate of the housing by screws or other means and the only movement it has is that given it by the swinging movement of the housing. Interposed between the hanger 2132 and an adjustable collar 236 on the rod is a spring 237 whose compression and expansion in opening and closing the housing, assisted by the chain and sprocket, eases the movement of the housing in both directions, there being an additional adjustable collar 238 on the rod to limit the forward movement of the rod and consequently the housing.

Power is supplied, any suitable kind of power but preferably that from an electric motor 2l9, whose shaft 222 has thereon two sprocket wheels 22d and 222', and from one sprocket runs a chain 225 that runs over the sprocket 226 on a shaft 227 having bearings in the side plates i and 2. From the other sprocketof the motor runs a chain 222 that runs over the sprocket 229 on the shaft 230 shown in Figures 2 and 6, and as shown in Figure 6, this shaft is geared with the shaft lli by means of a large continuously rotating sprocket 23E. on shaft lf3 anda sprocket 232 on the shaft 23B by a chain 233.

It is not deemednecessary to say much'more than thatl thepower .for the whole machine is supplied directly from the motor to the two sprockets 222 and 23@ and from .thence to other parts of the machine by means' of sprockets, chains and inter-meshing active and idler gears, all suitably formed, positioned and timed for coordinative action in the various functions they are called upon to perform, for instance from shaft 222, through chain 23V (Figure 10) and from shaft H2 through suitable intermeshing gears to the shaft`23 upon which the numeral Wheel assemblies are frictionally mounted, and

that the shaft ll, in the swinging front of the machine, gets its power through connections with shaft itl, etc.

The main bearings for the shaft 220i the vare in the side plates H0 and M, but since the shaft is long and carries numerous wheels, we have provided an open end bearing in the standard 28', Figure 4. The standard is provided with a base extension 239 which rests on a cross piece 24d extending 4between the plates 40 and 4l. This base has a hole through it for the passage of a screw 2M and the cross piece is provided with numerous threaded sockets, arranged in a row for the screws; thus this bearing becomes adjustable longitudinally of the cross piece 240, so that the numeral wheel shaft may be given additional support at any desired. point between its main end bearings. This bearing is about the width of three numeral Wheel assemblies and in mounting the various wheels, room is left on the shaft for the bearing, and this space on the` shaft also permits of the Wheel being slid or shifted longitudinally at any point" n the shaft to facilitate special wheel groupings, nd at the same time giving the shaft a bearing at the. point most needed in any particular push rod arrangement.
